Abstract (en)
[origin: WO2016090032A1] A high-capacity fluid pump comprising a dedicated lubrication system in fluid communication with the pump's drive assembly to reduce wear of internal components within the gearbox, as well as a drive shaft-supported impeller and outboard head to reduce deflection. Moreover, the blades of the outboard head are preferably shaped to decrease the inlet's cross section and stabilize incoming fluid, thereby reducing cavitation, pre-rotation, and turbulent flow at the pump inlet and increasing the overall velocity of incoming fluid.
